Xiaomi Notes can be installed and used on the mobile phone with the system installed, and the background can be freely changed. As for whether the password can be set, it depends on your mobile phone. Anyway, my Xiaomi can set the password. Xiaomi Post-it Notes is my most frequently used diary, and I use it to record all kinds of experiences, sentiments and instant inspiration every day. Not only that, Xiaomi Notes can also set time reminders so that you won't miss your schedule. Your diary can be backed up, so that your mental journey will never be lost.

3. China calendar
